See also Fig. 2, Fig. 2 is the schematic diagram of the device for displaying stereoscopic images 100 of demonstration 3-dimensional image of the present invention.Device for displaying stereoscopic images 100 comprises backlight module 102, display panel 140, polaroid (polarizing plate) 130, glass substrate 163 and one-quarter wavelength retardation film (λ/4 retarder plate) 170.Backlight module 102 can be straight-down negative light emitting diode (Light emitting diode, LED), and straight-down negative cold cathode ray tube (CCFL) or side-light type LED consist of.
One-quarter wavelength retardation film 170 has many first retardation plates 171 and many second retardation plates 172.Many the first retardation plates 171 and many second retardation plates 172 are alternative arrangements, and the angle of the optical axis direction of the first retardation plate 171 and horizontal direction A is 45 degree, and the angle of the optical axis direction of the second retardation plate 172 and horizontal direction A is 135 degree.Behind first retardation plate 171 of light through polaroid 130 and one-quarter wavelength retardation film 170 of right eye pixel column unit R ejaculation, can become right-circularly polarized light; Behind second retardation plate 172 of light through polaroid 130 and one-quarter wavelength retardation film 170 of left eye pixel column unit L ejaculation, can become left circularly polarized light.
Comprise the first retardation plate 171 and axis of homology perpendicular direction on the right eye eyeglass of the inclined to one side glasses 200 of circle in the polaroid 173 of horizontal direction A, comprise the second retardation plate 172 and axis of homology perpendicular direction on the left eyeglass lens of the inclined to one side glasses 200 of circle in the polaroid 173 of horizontal direction A.Therefore, the left circularly polarized light of formation can see through left eyeglass lens, and right-circularly polarized light can see through the right eye eyeglass.In the present embodiment, because Left-hand circular polarization only corresponds to the left eye signal, right-hand circular polarization only corresponds to the right eye signal, so the observer puts on the inclined to one side glasses 200 of circle, eyes just can be seen respectively different left-eye images and right-eye image, and perceive as at human brain and to have seen the 3D image.
See also Fig. 3, Fig. 3 is the schematic diagram of display panel, polaroid, glass substrate and rear the first embodiment of one-quarter wavelength retardation film combination of Fig. 2.The problem of crosstalking for fear of image and affect the effect of watching 3D, the present embodiment arranges a glass substrate 163 between one-quarter wavelength retardation film 170 and display panel 140, many light tight districts 165 are set on the glass substrate 163.After display panel 140, glass substrate 163 and one-quarter wavelength retardation film 170 were fitted, each light tight district 165 can be fitted on adjacent the first retardation plate 171 and the second retardation plate 172.The width in each light tight district 165 must be less than the width of right eye pixel column unit R or left eye pixel column unit L.Each light tight district 165 is that the position is in the side of glass substrate 163 near one-quarter wavelength retardation film 170.For fear of the aperture opening ratio that reduces pixel because of the width that increases black array layer 142b, so in the present embodiment, the width W 1 in each light tight district 165 is greater than the width W 2 of black array layer 142b, and is directly to be radiated at glass substrate 163 surfaces to form light tight district 165 with laser.Because the width W 1 in each light tight district 165 is greater than the width W 2 of black array layer 142b, because run through glass substrate 163 and is connected in black array layer 142b in light tight district 165, the corresponding light of right eye (or left eye) signal only can penetrate from the first retardation plate 171 (or second retardation plate 172).Even when watching with great visual angle, right eye (or left eye) signal can be stopped that can't pass through the second retardation plate 172 (or first retardation plate 171) penetrates by light tight district 165, thereby can improve the problem of crosstalking, and then affects the 3D image quality.
See also Fig. 4, Fig. 4 is the schematic diagram of display panel, polaroid, glass substrate and rear the second embodiment of one-quarter wavelength retardation film combination of Fig. 2.Be different from Fig. 3, Fig. 4 is to form light tight district 165 with Ear Mucosa Treated by He Ne Laser Irradiation glass substrate 163 inside.Run through glass substrate 163 and be connected in black array layer 142b in each light tight district 165, and the width W 3 in light tight district 165 is less than the width W 4 of black array layer 142b.Because run through glass substrate 163 and is connected in black array layer 142b in light tight district 165, the corresponding light of right eye (or left eye) signal only can penetrate from the first retardation plate 171 (or second retardation plate 172).Even when watching with great visual angle, right eye (or left eye) signal can be stopped that can't pass through the second retardation plate 172 (or first retardation plate 171) penetrates by light tight district 165, thereby can improve the problem of crosstalking, and then affects the 3D image quality.
Form the mode in light tight district 165 at glass substrate 163, also can be first after glass substrate 163 make a plurality of grooves by lithography, again with light-proof material, for example metal is formed on described a plurality of groove.
See also Fig. 2 and Fig. 5, Fig. 5 is the method flow diagram of the device for displaying stereoscopic images 100 that forms of the present invention.The method includes the steps of:
Step 500 a: one-quarter wavelength retardation film 170 and a display panel 140 are provided.One-quarter wavelength retardation film 170 comprises many first retardation plates 171 and many second retardation plates 172.Many the first retardation plates 171 and many second retardation plates 172 are alternative arrangements, and the angle of the optical axis direction of the optical axis direction of the first retardation plate 171 and the second retardation plate 172 is 90 degree.Display panel 140 comprises pel array 141, colored filter 142 and the liquid crystal layer 143 between pel array 141 and colored filter 142.Pel array 141 on the display panel 140 comprises many left eye pixel column unit L and many right eye pixel column unit.Many right eye pixel column unit R is alternative arrangements with these many left eye pixel column unit L.142 of colored filters comprise to show filter unit 142a and the black array layer 142b between any two adjacent filter unit 142a of Red,Blue,Green.
Step 502: form many light tight districts 165 at a glass substrate 163.Form surface that the mode in many light tight districts 165 can laser direct irradiation glass substrate 163 or inner to form a plurality of light tight districts 165 at glass substrate 163; Or elder generation is after glass substrate 163 makes a plurality of grooves by lithography, and again with light-proof material, for example metal is formed on described a plurality of groove to form a plurality of light tight districts 165.
Step 504: glass substrate 163 is fitted between one-quarter wavelength retardation film 170 and the display panel 140.Each light tight district 165 is fitted on adjacent the first retardation plate 171 and the second retardation plate 172, each light tight district 165 can be that the position is on the surface of glass substrate 163, near a side of one-quarter wavelength retardation film 170, or run through glass substrate 163 and fit in black array layer 142b in each light tight district 165.
The device for displaying stereoscopic images 100 that utilizes said method to make, each light tight district 165 can be used for stopping that the light that is penetrated by right eye pixel column unit R injects the second retardation plate 172, or stops that the light that is penetrated by left eye pixel column unit L injects the first retardation plate 171.Even so when watching with great visual angle, the corresponding light of right eye (or left eye) signal can be stopped that can't pass through the second retardation plate 172 (or first retardation plate 171) penetrates by light tight district 165, thereby can improve the problem of crosstalking, and then affect the 3D image quality.
